Abstract: 1,249,338. Water-tube steam generators; steam superheaters. COMBUSTION ENG. Inc. 6 Dec., 1968 [8 Dec., 1967], No. 58167/68. Headings F4A and F4B. In a vapour generator for a marine power plant having a generally rectangular setting with tubes for cooling its walls, a compartment 38 housing a reheater 14 and having burners 116 is located within the upper part of the setting and separated from the furnace chamber 34 with burners (78), Fig. 3 (not shown), and the convection section 36 housing a superheater 12 by a tubular gas impervious partition. The furnace chamber extends for the full height of the setting over part of the width and the partition extends rearwardlc from the front wall 48 of the setting to the boiler section 30. The partition is formed by the upper vertical portions of tubes 92 lining the lower part of the setting side wall 51 and tubes 108, Fig. 4, extending between the horizontal headers 64 and 94. The header 64, Fig. 5, communicates with the lower drum 42 and is attached to the front wall header 58. A diaphragm (65), Fig. 6 (not shown), isolates the rearward portion of the header 64, from which the tubes 108 extend, from the forward portion which is protected from the furnace gases by a portion 96, Fig. 5, of the tubes 92. The upper portions 72b of tubes 72, Fig. 2, lining the lower portion of the rear of the furnace chamber 34 are mutually spaced apart and screen the superheater 12 and reheater 14 from the radiant heat from the burners 78 and 116. The generator is vertically supported from the lower drum 42 of the boiler section 30 and the horizontal headers 58, 60 and 62 which are mounted at spaced points thereabout. The generator (11), Fig. 1 (not shown), supplies an ahead turbine (16) with high and low pressure stages, steam from the high pressure stage being reheated in the reheater (14) before being passed to the low pressure stage. When supplying an astern turbine (18) the operation of the burners 116 in the reheater compartment 38 is terminated.

Title: X-ray exposure control apparatus
IPC: H05G1/44
Filed: 1971-12-15
Abstract: 1370926 X-ray exposure control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 Dec 1971 [18 Dec 1970] 58240/71 Heading G1A [Also in Division G4] An X-ray exposure control device which operates by integrating a signal representing the intensity behind an object being radiographed and switching off the X-ray tube when a predetermined dose has been reached, includes circuitry to render the integrated signal logarithmic so as to facilitate pre-setting of the switch-off level. Fig. 2 shows the capacitor 1 which forms a voltage proportional to the dose received. The signal, once it has exceeded a reference level D 0  (which is 10% smaller than the smallest switch-off dose required) set into operational amplifier 3, is rendered logarithmic by a feedback loop associated with the amplifier. The signal is then quantized by circuit 5-9, and when the number of pulses generated (in proportion to dose) exceeds the level set in counter 10 by means of pre-setting device 11, the switch-off pulse S is produced. The system may alternatively operate without quartizing, in which case just a few switch-off voltages are selectable. The detector may be an ionization chamber.

Patent GB-765797-A (GB)
Abstract: 765,797. Stereo-photogrammetric apparatus. ZEISS - AEROTOPOGRAPH GES. May 31, 1954 [June 13, 1953], No. 16019/54. Class 97(1) Approximately vertical axis aerial photographs are set up on a stereophotogrammetric plotter as if they were truly vertical views and it is stated that a pair of photographs of a plane surface produce, when stereoscopically viewed, a curved surface represented approximately by the equation Z = ax + by + cxy + d (where a, b, c, d, are constants) so that contours can only be correctly drawn if the height correction Œ Z is added to the height corresponding to the actual'distance apart of two stereoscopically fusable marks 60, 61 for each point in the photograph. According to the invention the values x, y, each corresponding to a point on the photographs, are automatically set on computer as the marks 60, 61 are moved over them and the computer indicates the value of Z and/or adjusts one mark 61 with respect to the other 60 through distances equal to the correction which Z undergoes on varying x and y. Preferably, the constants a, b, c and d are set on the computer by means of guides 14, 15 and, as shown in Fig. 1, slide 1 and carriage 30, carried thereon, move in mutually perpendicular directions so that pointers 3 and 31 automatically record the x and y co-ordinates of any point in the photograph. The indination of the beam 26 is uniquely determined by the position of slide 1 on rail Z and the value indicated by the pointer 34 is determined by the sliding contact between member 33 and beam 26. Mark 61 is moved relatively to mark 60 through bell crank lever 72 and micrometer screw 62 is used for the initial adjustment of the spacing of the marks. If the constants a, b, c, d are chosen so that one guide 14 or 15 is parallel to the direction of motion of slide 1, the beam 26 may be pivoted to the slide 1 at one end 24 or 25 respectively. If the correct spacing for the marks 60, 61 is known for four points in the photograph mark 60 may be adjusted to each of the four points in turn and one end of each guide 14, 15 moved at each point until the stereoscopically fused marks touch the ground at all four points. The apparatus is then set up for plotting contour lines by means of a pen attached to mark 60. Another form of the apparatus (Fig. 5) is adapted for a cylindrical surface derived from the previous equation by putting y = x. The axis of the cylinder is parallel to the axis of y and the Z correction for any point on a genatrix is the same for all points on the genatrix, so that it is not necessary for the spacing of the marks to be variable with respect to the y direction. As shown in Fig. 5, carriage 30 is displaceable in the x direction only and, a displacement of x moves slide 1 (carrying beam 26) through a distande x/2 in the same direction.

A low-pressure compressor 2 driven by a turbine 8 through reduction gearing 8c supplies air to a highpressure compressor 1 and to a duct 6 leading to an annular discharge nozzle 15. The highpressure compressor 1 supplies air to a combustion chamber 7 feeding the turbine 8. The duct 6 contains a number of pulse jet units each comprising a pulsatory combustion chamber 10, an aerodynamic inlet valve 11 and exhaust pipe 13. The exhaust pipes 13 discharge into ejectors 17 which also receive some of the air passing through the duct 6 around the pulse jet units. The remainder of the air passes around the ejectors to the annular discharge nozzle 15. To augment the thrust fuel injectors 38 are arranged to discharge into the forward part of the ejectors. The ignition is automatic when the chambers 10 are in operation. Normally the wake caused by the ejectors is sufficient to stabilize the flame but stabilizing screens may be provided if necessary. The injectors 38 may be arranged on the upstream side of the ejectors between the outlets of the pipes 13 and the inlets of the ejectors, in the pipes 13 or in the divergent portions 36 of the ejectors. The supplementary fuel may be injected at low pressure without atomization and the injectors may be simple freely open tubes which may be directed in any direction into the gas flow.

Title: Milking method and apparatus
IPC: A01J5/017
Filed: 1978-11-13
Abstract: In order to apply teat cups automatically, or facilitate their application by hand, each teat cup is associated with a support surface 28 projecting to one side of the top of the cup. The cup with the support surface trailing, is moved laterally against a teat until this lays on the support surface, after which movement is reversed while suction is applied to the cup, so that the teat falls and is sucked into the cup. A machine for carrying out the method can be controlled in response to signals from an electronic camera, touch or proximity sensors on the teat cup, and a vacuum sensor signalling entry of a teat into the cup. The machine has means for grasping an individual teat cup and moving it into engagement with a teat. The support surface 28 is carried by a sleeve 26 spring-urged into the full line position. When a teat is properly inserted into the teat cup the increase in vacuum in the interior of the liner 14 is applied to a space 40 between the sleeve and the teat cup shell 11 and shifts the sleeve and support surface 28 downwardly to the phantom line position. <IMAGE>
